WALKING-PLOW.

Specification of Letters Patent.

Patented May 9, 1916.

Application led November 9, 1915. Serial No. 60,582.

To all tlf/1,0m t may concern c Be it known that I, BoNrFAnro ARrsTosA,

a citizen of the United States, residing at Iloilo, in the Province of Iloilo, Philippine Islands, have invented certain new and useful Improvements in VValking-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in 'the art to which it appertains to make and use the same. n j

This invention relates to new and useful improvements in plow structures, particularly of the type embodied in Patent #1,020,232 granted to A. Varges, March 12, 1912.

It is the object of the present invention to so pivotally mount the plow beam that the angle of the beam with relation to the handle portion of 'the device, which determines the depth at which the plow point works, may be adjusted by the operator asy desired while -working the plow, and without the necessity of providing any means for locking the beam, this advantage being procured by so securing 'the beam that a greater leverage may be had by the handle portion of the plow. It is desirable'to state that the present plow structure is of light type and is adapted for use under such conditions described in the said patent wherein an easily worked soil is found.

It is further an object to provide such a modified structure which may be very readily adapted to the plow inthe previous patent.

lVith the above and other objects rand advantages in view, the invention resides more particularly in the novel combination, formation and arrangement of partspas more fully described hereinafter and pointed out in the appended claim.

Reference is had to the accompanying draw ings, wherein similar characters ofreference designate corresponding lparts throughouty the several views, and in which Figure 1 1s aside elevation of the 1mproved plow structure, showing an adjusted position in dotted lines; Fig. 2 is a top plan View of the plow structures; Fig. k3 is a vertical sectional view taken on the line 3 3 of Fig. l.

Referring now more particularly to the accompanying drawings there is shown a plow of the general structure embodied in theV aforesaid patent to Varges and comprising the land side 5 carrying a mold board 6.

A plow stock 7 extends upwardly from the forward end of the land side and ahandle bar extends vdiagonally upward from lthe rear end thereof. A plow beam 9 is provided, but this beam instead of being pivot'ed to the plow stock is pivoted to the han-` dle bar a't l0 and has its intermediateportion slidably held adjacent the plow stock by a. bracket comprising ya metal strap having 1s ends olfset inwardly and bolted at l2 to the said stock. vThus in the operation of the plow, the pressure exerted by the operator on the handle bar determines the depth at which the mold board works and as this pressure is varied, the depth of the mold board is adjusted. This operation could perhaps be obtained in the plow emt BONIFARIO ARISTOSA.
